Solution:-

Step 1:-

Subtract numbers under ones.

Mathematics, Showing subtraction by borrowing method.

5 is smaller than 7. So borrow 1 from tens, ie, 10. Now, 5 will become 15. Subtract 7 from 15 and write it under ones.

Step 2 :-

Now, tens gave one, so 2 become 2-1 = 1.Subtract number under tens.

This subtraction is showing as a whole below:-

or

You can simply write it as 25 – 17 =8

Always remember that

 1 ones = 1

2 ones =2

And

1 tens = 10

2 tens =20

1 hundreds = 100

2 hundreds = 200

1 thousands = 1000

2 thousands = 2000

So, borrowing 1 from tens means 10.

Add this 10 to number at ones place and subtract numbers at ones place.
